Description

Die Erfindung betrift't einen Drehstuhl mit verstellbarem Sitz, dessen Tragstange durch den Klemmdruck einer Schelle feststellbar ist, und besteht darin, daß bei Benutzung einer einstellbaren Gewindespindel als Sitztragstange eine unterteilte Mutter zur Übertragung des Klemmdruckes der Schelle auf die Sitzspindel vorgesehen ist.The invention concerns a swivel chair with an adjustable seat, the support bar through the clamping pressure of a clamp can be determined, and consists in that when in use an adjustable threaded spindle as a seat support rod a subdivided nut for transmission the clamping pressure of the clamp on the seat spindle is provided.

Auf der Zeichnung ist die Erfindung in ίο einem Ausführungsbeispiel dargestellt, und zeigtIn the drawing, the invention is shown in one embodiment, and shows

Abb. ι die Feststellvorrichtung im Längsschnitt undFig. Ι the locking device in longitudinal section and

Abb. 2 einen Querschnitt nach der Linie A-A der Abb. 1.Fig. 2 shows a cross section along the line AA in Fig. 1.

In der Führungshülse a, die die Befestigungsstücke b, c zur Aufnahme der Stuhlbeine trägt, ist die den Sitz tragende Spindel e in einem im oberen Teil angebrachten Gewinde geführt. In ihrem unteren Teil d ist die Hülse α erweitert und dient zur Aufnahme des Klemmittels e. Dieses besteht aus einer unterteilten, in den Gewindegang der Spindel e' passenden Mutter / und, einer daruma5 gelegten Schelle h, die zwecks besserer Federung nach der offenen Seite hin stärker gestaltet ist. Die Mutter / und die Schelle h werden durch eine Schraube i festgehalten, die in einer Bohrung des Ansatzes d der Hülse α sitzt. Die Schelle h wird durch die Flügelschraube η zusammengezogen, die in die hintere Lasche m der Schelle Ii mit Gewinde eingreift. Durch Anziehen der Schraube i wird durch Vermittlung der Schelle h die Mutter f mehr oder weniger zusammengepreßt, so daß sie die Spindel e einklemmt und die Spindel in der gewünschten Sitzhöhe feststellt.In the guide sleeve a, which carries the fastening pieces b, c for receiving the chair legs, the spindle e carrying the seat is guided in a thread made in the upper part. In its lower part d , the sleeve α is expanded and serves to accommodate the clamping means e. This consists of a subdivided nut / nut that fits into the thread of the spindle e ' and a clamp h placed around it, which is designed to be stronger towards the open side for the purpose of better suspension. The nut / and the clamp h are held in place by a screw i which is seated in a hole in the shoulder d of the sleeve α. The clamp h is pulled together by the wing screw η, which engages in the rear flap m of the clamp Ii with a thread. By tightening the screw i , the nut f is more or less compressed by means of the clamp h , so that it clamps the spindle e and fixes the spindle at the desired seat height.
